Chipmakers hoping to tap into the Biden administration’s $39 billion semiconductor manufacturing subsidy program will need to sign agreements promising they won’t expand production capacity in China. The requirement was among a handful of funding conditions the US Commerce Department outlined this week after announcing it would begin accepting applications for money from the CHIPS Act in late June. Congress passed the $280 billion measure last July in a rare show of bipartisan cooperation and set aside $52 billion in tax credits and funding for US semiconductor firms to expand domestic production.
